OIL-TESTER.

Specification of Letters Patent.

Patented Apr. 16, 1918.

Application filed August 14, 1915. Serial No. 45,465.

To all whom t may concern:

Be it known that I, CHARLEs J. Trienni- BUE, a citizen of the United States, and resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful improvements in Uil-Testers, of which the following is a specification.

My invention relates primarily to open testers for testing the flash point and the point at which the oil will take fire. Open testers of this type are usually provided with a wire rest across the top'of the oil cup over which a burner tip provided with a small ignition flame is adapted to be drawn in order to ascertain the flash point of the oil being tested. It has been found that with testers of this kind errors may arise, because different experimenters or even the same experimenter at dierent times can not be expected to pass the testing flame over the oil every time at the same distance above the surface of the oil.

rlhe object 0f my improvement is to provide the oil tester with a gas burner adapted to be permanently supported at a fixed distance above the oil cup so that it may be swung across the top thereof in a horizontal plane thus insuring like conditions for all tests. I have also provided means for regulating the size of the flame and a suitable gage with which to compare the flame in order that a standard size for the flame may be maintained during the various 0r repeated tests that may be made.

I have illustrated one adaptation of my improved device in the accompanying drawings in which Figure 1 represents a side elevation of an open tester of the usual form and Fig. 2 is a top plan view thereof.

Referring to the drawings 1 represents the base of the tester which is adapted to support a waterbath 2 in which an oil cup 3 is adapted to dip substantially as indicated by the dotted lines in Fig. 1. One side of the bath is preferably provided with a binding post or stud l and a wire runner 5 through which a supporting rod or wire 6 is' adapted to pass, the lower end of the wire being clamped by means of an adjusting screw 7. The upper end of the wire 6 is bent over the oil cup 3 and is provided with a hook at 8 from which a thermometer 9 is suspended, the lower end of the thermometer being adapted to enter the oil in the oil cup 3 and give the temperature thereof while making the test.

At one side of the bath 2, I preferably secure a bracket or support 10 having a tubular bearing 11 secured thereto and eX- tending in a vertical direction substantially parallel with the axis of the bath. A gas tube 12 is rotatably mounted in the bearing 11, the upper end being enlarged at 13 so as. to provide a shoulder resting upon the t-ubular bearing 11 at 14 to support the same in a fixed position. The upper end of the gas tube is preferably extended by an elbow joint at-15, one arm of which extends horizontally or substantially at right angles to the tube 12 and is provided with a burner tip at 16 where a small testing flame 17 is adapted to be produced. The elbow 15 is preferably threaded at 16 and screwed into the upper end of the enlarged tubular portion 13 of the gas tube 12. rlhis threaded connection at 16 between the burner and the gas tube .enables one to adjust the position of the burner tip above the surface of the oil in the cup when so desired. ln making the test for the fiash point of the oil under consideration it is necessary to swing the burner 16, with its small flame tip, horizontally across the top of the oil cup 3 from time to time, taking the temperature each time by reading the thermometer. ln order to swing the burner horizontally over the oil cup I preferably provide the gas tube 12 with a short horizontally y'projecting handle 18 which is preferably connected with the tube through a slot 19 in the tubular bearing l1, the end walls of the slot being adapted to limit the turning movement of the tube and burner to about 18()O as indicated in Fig. 2 of the drawing. lt'will be understood, however, that other suitable means for swinging the burner horizontally and for limiting its movement, may be employed. In order to insure uniformity of the tests it is necessary that the flame tip be of a constant or uniform size and in order to gage the size thereof I provide the outer end of the arm 18 with a small sphere 20 adapted to indicate to the eye of the observer the size to which the fiame tip 17 should be adjusted. ln order that this adjustment may be readily made the lower end of the gas tube 12 is preferably provided with a stop cock 21 which may be readily turned to vary the flow ci' gas, and hence controls the size of the gas flame at 17. The lower end of the stop cock member 2l at 22 is provided with a nipple i'or attach ing thereto a rubber tube 252 lwhich may be connected with a source of gas supplied in the usual or any preferred manner. rlhe bath 2 is heated in the usual manner by an alcohol lamp 2a or other suitable means as may be required or desired.

lt will be understood that various modifications in the specific details ci my improvement may be made without departing from the spirit and scope ot the invention.

i claim:

l. ln an open tester for cils the combination with a water bath lnaving` an open oil cup therein, of a bracket support on said water bath and a gas tube rotatably mounted in said bracket support said tube being` provided with a burner tip adapted to be swung in a horizontal plane over said oil cup.

2. in an open tester for cils the combination with a water bath having` an open oil cup therein, ot a bracket support .on said water bath, a gas tube rotatably mounted in said bracket support, and means co-acting between the burner tube and said bracket to limit the rotary movement of said 'tube in either direction, said tube being provided with a burner tip adapted to bel swung in a horizontal plane over said oil cup.

3. ln an open tester for oils the combination with a water bath having an open oil cup therein, of a bracket support on said water bath, a gas tube rotatably mounted in said bracket support, a burner tip connected with said tube, and means for turning' said tube to swing said burner tip over said @il cup in a horizontal plane.

4f. ln an open tester for oils the combination with a water bath having an oil cup therein, ci a bracket secured to the side of said bath, a vertically disposed tubular bearing` on Said bracket7 a gas tube rotatably mounted in said bearing, a burner tip projecting horizontally from said tube adapted to clear the top oit said cup means for maintaining said burner tip at a predetermined iiXed distance above said cup and means meshes rotating said tube to swing the burner tip horizontally across the top or' said cup.

5. ln an open tester for oils the combinaion' with a water bath having' an oil cup herein, ci a bracket secured to the Side of Jaid bath, a vertically disposed tubular caring on said bracket, a gas tube rotatably mounted in said bearing, a burner tip projecting` horizontally from said tube adapted to clear the top of said cup means for main taining` said burner tip at a predetermined lined distance above said cup, a stop cock in said tube for regulating,` the size of1 the flame at the burner tip and means for rotat-V ing said tube to swing the burner tip horizontally across the top of said cup.

6. ln an open tester for oils the combination with a water bath haviiig` an oil cup4 therein, oil a gas tube vertically disposed along; the side oit said bath, means projecting; irom the side of the bath for rotatably supporting' said tube, a burner tip extending horizontally from the upper end or' said'tube and adapted to be swung across the top of said cup a iinger lever connected with said tube for rotating` the same, said lever being provided with a knob adapted to serve as a tor the size of the Haine at the burner tip and a stop cock in said tube for adjustinn; the size of the liame.`

'a'. ln an oil teste-r, a Water bath having` an open oil cup therein, a burner tip adapted to be moved across and above said oil cup, means confining said movement toa definite horizontal plane, a lever connected` with the burner ltip for manipulating YSaid tip said lever having a knob adapted tov serve as a for the size of the flame, and means for adjusting the size of the flame.

8. ln an oil tester, a water bath havingan open oil cup therein, a burner tip adapted to be moved across and above said oil cup, means confining` said movement to a definite horizontal plane, a knob adjacent to the burner tip to serve as a gage for the size of the flame, and means for adjusting` the size of the ilame'. Y

ln testimony whereof l have hereunto set my hand.
